Does a fountain send forth at the same hole the sweet and the bitter?
As a fountain keeps fresh her waters, so she keeps fresh her evil; violence and spoil is heard in her; always before Me are grief and wounds.
Out of the same mouth proceeds blessing and cursing. My brothers, these things ought not to be so.
Can the fig tree, my brothers, bear olive berries; or a vine, figs? So no fountain can yield both salt water and fresh.
